Note: 1. The specification for VA rating may be exceeded for less sensitive (High AT) switches, and should be decreased

for very sensitive (Low AT) switches. Specific life testing for a particular load will be run upon request.

2. Breakdown voltage is measured in the presence of a radioactive ionizing source with leakage current limited to

100 microamperes.
